My invention relates to thread carrying cones used in the textile art, such cones being constructed and adapted to receive and sup-' port, a load of thread wound thereon in close formation. It is designed particularly for use in the winding of silk threads, and may be loaded by the action of any of-the modern, high-speed, silk winding machines. After loading, the cone with the mass of thread wound thereon, is associated with a knitting machine, or other textile 'fabricating machine, and the thread is drawn from the cone and fed to the machine in-the progress of the production of a stocking or other textile. However, while particularly designed foriuse in connection with the fibrous material referred to, it is to be understood that the usesof the invention are not to be so limited, and that they are susceptible of general application and use in the art to which the invention appertains.

Considerable annoyance has been exper ienced heretofore in many instances in'which the frictional engagement of the load of thread with the cone is interrupted in the operations of transporting and handling panes, especially those loaded with silk threads, or their substitutes and imitations,

b reason of the natureof these materials.

1 en such a'situation occurs, the delivery of the thread from. the cone to the machine in the fabricating operation is not satisfac- I tory. The light tension to which the thread the operation of winding it detracts from a firm union is subjected in upon the cone,

between-theinitlal courses of the thread and the surface of the cone, and the weakness developed at this point is frequently the source 6 of a later annoyance.

My improved cone has been; produced with a view to overcoming the unfavorable situation referred to, and by its 'usel achieve a surer engagement of the load of thread with the cone, by a particular formation of the surface of the latter. By this means, a better engagement of the thread with the cone is efiected, so that the load is more stably posi- ,tioned upon the cone, and a uniform delivery of the thread at all times, in the fabricating operation, is secured.

Th1 forming the im roved cone, I provide upo the exterior sur ace of the same, a plurahty of circumferential embossments or ribs, varying progressively in elevation from the surface of the cone, starting from a point greater degree, when an axial movement with respect to the cone is unintentionally imparted to the load of thread. This improvement by increasing the anchorage of the load greatly au ments the frictional engagement between th ,load and the cone, and the com- 'bined action contributes to the attainment of the result desired.

In the process of fabricating a textile, superior. results flow from the use of threads possessed of a modicum of moisture, as is well known in the practice of the instant art. Hence, another'adjunctiye feature entering into the construction of my improved cone, enables me to apply moisture directly and efficiently to the load of thread wound upon the cone. In attaining this result, I provide the surface of the cone with circumferential rows of perforations, preferably equal in number to the circumferential embossments or ribs before referred to. In applying moisture, the loaded cone is inverted, base upward, and a quantity of water poured into the open interior of the cone. The water seeps through the perforations, and permeates in an even degree, the thread wound upon the cone.

Having thus outlined the nature and purposes of my invention, 1 will now describe the specific form of constructionin which it has been embodied, and in the appended claims will point out the novelty residing therein.

The accompanying drawing is an isometric 9 a load of thread laid thereon by any desired 10 manner of winding, so that the load of thread is built up as a compact mass. I prefer to produce the cone from sheet aluminuni of suitable gauge, and it may be formed by 5 drawing, stamping and seaming, or spinning, as may be convenient. The base of the cone may or may not be provided with a finishing circumferential head 11, as desired, and the apex 12 will be slightly rounded in the manufacturing operation, thus forming a thin, metal cone, open at its base to constitute a hollow interior and closed at its apex. Commencing a short distance below the apex of the cone, I'form upon the outer surface ofthe cone, a series of spaced circumferential embossments or ribs, the upper one of which is indicated 13. These embossments or ribs progressively increase in the extent of their elevation with respect to the outer surface of the cone as the diameter of the latter increases, until the embossment or rib 14 nearest the base of the cone presents the highest desired elevation. The intermediate embossments or ribs 15 partake of the gradual increase from the lowest embossment 13 to the highest embossment 14. y r In the drawing, I have shown at the opposite sides of the cone 10, two diverging dotted lines, 'which it will be seen depart from parallelism with the sides of the cone, running toward the base of the latter, to n rore clearly indicate the progression in the increase'in the elevation of the plurality of embossments above the surface of the cone. As has hereinbefore been indicated, the purpose of forming the series of circumferential embossments of progressively increasing elevation, is to enlarge the anchorage of the load upon the cone and render it more stable, as by deepening the bight at the lower end of the cone. The mass of thread is sometimes subjected to unintentional axial movement toward the apex of the cone, due to the lack of resistance in the frictional engagement of the thread with the cone, and such movement is energized by the im ulse of the rear part of the mass of threa which acquires a slight momentum in such movement. But by deepening the bight of the thread upon the cone, as'by the increased entry into the mass of thread by the circumferential embossments of greater altitude, the tendency to mass movements and the acquirement of momentum is lessened, with the result that the shifting tendency heretofore experienced is overcome, and stability of the load in its relation to the cone is secured.

In the operation of producing a textile, better results are secured when the thread is in-a slightly moistened condition. n approved method of applying the desired moisture to the thread, is to introduce moisture into the mass of thread after it has been wound upon the cone. 1 This may be conveniently done by providing the surface of a quantity of water poured into the hollow the cone with a plurality of perforations 16, arranged in spaced circumeferential rows, alternating witlf the circumferential embossments, the number of rows and number of embossments being preferably equal. The diameter of the perforations 16 progressively increases, commencing with the row of perforations nearest the apex. The loaded cone will be inverted with its base uppermost, and

interior thereof. The moisture will pass outwardly through the perforations and permeate the thread constituting the load. After the permeation has reached an approved degree, the cone may then be transferred to the textile machine, and fed thereto in the production of a textile.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

1. A cone constituted of metal closed at its apex and open at its base to present a hollow interior, the said cone being provided upon its exterior surface below the apex with a plurality of circumferential embossments or ribs of progressively increasing elevation with respect to the said surface.

2. A cone constituted of metal closedat its apex and open at its base to present a hollow interior, the said cone being provided upon its exterior surface below the apex with a plurality'of circumferential embossments or ribs of progressively increasing elevation with respect to the progressively increasing diameter of the cone.
